Crystal Green® is the first continuous release fertilizer to provide Root-Activated™ phosphorus, along with nitrogen and magnesium, (5-28-0 with 10%Mg), to feed potato plants in one season-long application.
As a source of phosphorus, Crystal Green represents a true innovation in the fertilizer sector due to its unique mode-of-action. Unlike conventional phosphorus fertilizers, which are water soluble, Crystal Green uses a citrate soluble mode of action activated by organic acid production. As the roots produce citrates, Crystal Green responds with a healthy release of phosphorus to feed the plants. As plant demand decreases, nutrient release from Crystal Green is reduced, minimizing excess phosphorus in the soil and lowering the risk of tie-up, leaching and runoff. This mode of action allows Crystal Green to meet the nutrient requirement of your potato plants all season long.
Crystal Green is recognized under the USDA Conservation Stewardship Program as an approved nutrient input, a 4R Nutrient Stewardship Partner, and an Association of American Plant Food Control Officials (AAPFCO) approved source of slow-release nutrients.
